Design and analyze satellite constellations and distributed space architectures. Use this skill for Walker constellation patterns, coverage analysis, inter-satellite links, orbital shell design, collision avoidance, spectrum coordination, and deorbit compliance. Trigger for "constellation," "Walker pattern," "coverage analysis," "orbital shell," "inter-satellite link," "ISL," "revisit time," "ground coverage," "mega-constellation," or "distributed architecture."
Perform parametric cost estimation and ROM (Rough Order of Magnitude) costing for space missions. Use this skill to generate lifecycle cost estimates using CERs, compare launch costs, estimate operations budgets, and support cost-driven trade studies. Trigger this for "cost estimate," "ROM cost," "mission cost," "launch cost," "cost model," "lifecycle cost," "operations cost," or whenever a trade study needs cost as a Figure of Merit.
Perform Environmental Control and Life Support System (ECLSS) sizing and analysis for crewed spacecraft, stations, and habitats. Use this skill to size O₂ generation, CO₂ removal, water recovery, thermal/humidity control, and habitable volume. Trigger for "life support," "ECLSS," "crew systems," "O2 generation," "CO2 scrubbing," "water recycling," "habitable volume," "cabin pressure," or "crew consumables."
Define Flight Software (FSW) architectures, C&DH hardware requirements, and modern DevOps practices for space. Use this skill to size processors, estimate memory, plan software tasking, design FDIR strategies, plan CI/CD pipelines, set up simulation-in-the-loop testing, and define automated test infrastructure. Trigger this for "FSW architecture," "processor sizing," "data handling," "FDIR design," "onboard computer selection," "CI/CD for flight software," "simulation in the loop," "DevOps for space," or "automated FSW testing."
Design and assess ground segment infrastructure for space missions. Use this skill to plan mission control centers, ground station networks, launch facility requirements, GSE design, and range safety. Trigger for "ground systems," "mission control," "ground station," "GSE," "ground support equipment," "launch pad," "range safety," "mission operations center," "telemetry tracking," or "ground segment."
Perform In-Situ Resource Utilization (ISRU) sizing and feasibility analysis. Use this skill to evaluate resource extraction from planetary regolith, propellant production from local materials, water ice mining, and closed-loop resource economics. Trigger for "ISRU," "in-situ resources," "regolith processing," "propellant production," "water ice extraction," "lunar mining," "Mars ISRU," "Sabatier reactor," or "oxygen from regolith."
Assess spacecraft manufacturability, production planning, and fabrication trades. Use this skill for Design for Manufacturing (DFM), Design for Assembly (DFA), make-vs-buy decisions, production rate analysis, and vertical integration trades. Trigger for "manufacturability," "DFM," "DFA," "production rate," "make or buy," "fabrication," "assembly sequence," or "vertical integration."
Analyze reusability of launch vehicles and spacecraft systems. Use this skill to size recovery hardware, estimate refurbishment costs, model reuse degradation, and calculate flight-rate economics. Trigger for "reusability," "landing propellant," "recovery system," "refurbishment," "turnaround time," "flight rate economics," "booster recovery," or "reuse degradation."
